Ultra-rare whale never seen alive washes up on on New Zealand beach — and scientists could now dissect it for the 1st time

A mysterious dead whale that recently washed up on a New Zealand beach may belong to the world's rarest cetacean species, spade-toothed whales, which are so elusive they have never been seen alive. If this is the case, the newfound specimen will give scientists a rare chance to study the creatures we know next to nothing about.
Beachgoers discovered the 16.5-foot-long (5 meters) carcass July 4 on the shore near Taieri Mouth — a village in the Otago region of New Zealand's South Island. Wildlife experts from the country's Department of Conservation (DOC), recovered the remains and took DNA samples, which have been sent to the University of Auckland for analysis, according to a DOC statement .
Researchers from DOC and the Museum of New Zealand Te Papa Tongarewa believe the animal is a spade-toothed whale ( Mesoplodon traversii ). However, they will not know for sure until the DNA samples are analyzed, which could take "several weeks or months," DOC representatives said. The remains are currently being preserved in cold storage.
If confirmed, the newly washed-up whale will be the sixth known spade-toothed specimen found in the last 150 years, of which only two others have been fully intact. To date, there have been no confirmed live sightings of the species.
"Spade-toothed whales are one of the most poorly known large mammalian species of modern times," Gabe Davies, a DOC coastal operations manager for Otago, said in the statement. "From a scientific and conservation point of view, this is huge."
Spade-toothed whales were officially described in a 2002 study , which revealed that three whale bones found in New Zealand and Chile between 1873 and 1993 shared the same DNA that was unknown to science. The first intact specimens were found in 2010 when a suspected mother and calf washed up dead at Opape Beach in New Zealand's North Island.
If the new specimen is a spade-toothed whale, this will be the first chance that researchers have to dissect the species because the other intact specimens that washed up at Opape Beach were buried before genetic analysis confirmed their identity, AP News reported — meaning the opportunity to study them was lost.
Any dissection of the specimen will be carried out under the supervision of the local rūnaka — a Māori tribal council, DOC representatives wrote. This will be done to honor a non-legally-binding treaty signed by Māori leaders and several Polynesian Indigenous groups in March , which recognizes whales as "legal persons."
